Reaction and remarks from Biden's visit to Ukraine

Following are comments and reaction from U.S. President Joe Biden's surprise visit to Ukraine on Monday.

"As the world prepares to mark the one-year anniversary of Russia's brutal invasion of Ukraine, I am in Kyiv today to meet with President Zelenskiy and reaffirm our unwavering and unflagging commitment to Ukraine’s democracy, sovereignty, and territorial integrity.

"When (Russian President Vladimir) Putin launched his invasion nearly one year ago, he thought Ukraine was weak and the West was divided. He thought he could outlast us. But he was dead wrong.

"I will announce another delivery of critical equipment, including artillery ammunition, anti-armor systems, and air surveillance radars to help protect the Ukrainian people from aerial bombardments.

"Later this week, we will announce additional sanctions against elites and companies that are trying to evade or backfill Russia's war machine.
